* Various pages that formerly lacked the information now have
a note under RETURN VALUE that errno is set on error.
* Peng Haitao has submitted patches to around 50 pages that note
functions that are thread-safe or thread-unsafe. For this
purpose, the man-pages add a new section, ATTRIBUTES, as
described in the man-pages(7) manual page. Peng Haitao's
substantial work is ongoing, and more pages will add this
information in the future.

epoll_wait.2
Describe timeout limitation in kernels < 2.6.37
As reported by Fredrik (and as far as I can tell the problem
went back to 2.6.0):
The timeout argument has an upper limit. Any values above that
limit are treated the same as -1, i.e. to wait indefinitely.
The limit is given by:
#define EP_MAX_MSTIMEO min(1000ULL * MAX_SCHEDULE_TIMEOUT / HZ, \

Global fix: use UR macro where applicable
The syntax .UR http://example.com paired with .UE will create
links which one can interact, if the pager allows that. One
way to see the effect is ask the man(1) command to use browser
display, e.g.:
man -H man7/uri.7

explicit requirement that these arguments be "int".

nfsservctl.2

ptrace.2
add extended description of various ptrace quirks
Changes include:
s/parent/tracer/g, s/child/tracee/g - ptrace interface now
is sufficiently cleaned up to not treat tracing process
as parent.
Deleted several outright false statements:
- pid 1 can be traced
- tracer is not shown as parent in ps output
- PTRACE_ATTACH is not "the same behavior as if tracee had done
a PTRACE_TRACEME": PTRACE_ATTACH delivers a SIGSTOP.
- SIGSTOP _can_ be injected.
- Removed mentions of SunOS and Solaris as irrelevant.
- Added a few more known bugs.
Added a large block of text in DESCRIPTION which doesn't focus
on mechanical description of each flag and operation, but rather
tries to describe a bigger picture. The targeted audience is
a person which is reasonably knowledgeable in Unix but did not
spend years working with ptrace, and thus may be unaware of its
quirks. This text went through several iterations of review by
Oleg Nesterov and Tejun Heo.

SYNOPSIS: Add "#include <fntl.h>" for O_* constants

Substantial restructuring of DESCRIPTION
The addition of a second class of operation ("hole punching")
to the man page made it clear that some significant restructuring
is required. So I substantially reworked the page, including the
preexisting material on the default "file allocation" operation.
